it listens, then it plays.
insert stems on a track in logic pro — or any audio unit host. press play. it records up to two minutes of your take, kept to whole bars at your tempo. stop when you’re done.
then ask for a part. drums and bass are the strong ones right now. melody and vocals run, but they’re still rough, and we say so. describe it in the model’s own words — “emo rap, cloud rap. bright, sparse drums.” — and a take arrives, looping against your track inside the plug-in.
keep it, or refine it: same musician, your edited description. when it sits right, drag it out. it lands on your timeline as a plain wav region. no export, no project format, nothing to keep alive.
no text box. no subscription. no company.
- not text-to-song. the session is the prompt. the music comes from what you played; the words only steer the timbre of the part.
- not a daw. your daw arranges. stems hands it audio and gets out of the way.
- not a product. free, with no subscription coming later. it’s a non-commercial research project by one person — an instrument, not a company.
one gpu, fifty takes a day, and the truth about the data.
it runs on a single gpu. a take takes a minute or two, and the first one of the day can take longer while the machine wakes up. if it’s slow or down, that’s why. every person gets 50 generations a day.
your uploads and the takes you generate may be used to train future versions of the model. that’s the trade that keeps it free, and it’s written in the terms in plain language. you keep every right to what you upload and to the stems made from your material.
a mac, a host, an email.
- macos 13 or newer.
- an audio unit host. it’s been used most in logic pro; any host that loads au plug-ins can load it.
- an email address — sign-in is a link, there’s no password. one key per person.
